    [+In] RelationalExpression[+In, ?Yield, ?Await] in ShiftExpression[?Yield, ?Await]

  [...]

  1. Let lref be the result of evaluating RelationalExpression.
  2. Let lval be ? GetValue(lref).
  3. Let rref be the result of evaluating ShiftExpression.
  4. Let rval be ? GetValue(rref).
  5. If Type(rval) is not Object, throw a TypeError exception.
  6. Return ? HasProperty(rval, ? ToPropertyKey(lval)).
